Brain–computer interface (BCI), often called a mind-machine interface (MMI), or sometimes called a direct neural interface or a brain–machine interface (BMI), is a direct communication pathway between the brain and an external device. BCIs are often directed at assisting, augmenting, or repairing human cognitive or sensory-motor functions. It is also sometimes called “telepathic computing.” — Wikipedia

Scientists have detailed a less invasive method of neural stimulation that would use an untethered ultrasmall electrode activated by light, a technique that may mitigate damage done by current methods. […]

Researchers applied a machine learning technique that could potentially translate patterns of activity in fear-processing brain regions into scores on questionnaires used to assess a patient's fear of pain. This neuroscientific approach may help reconcile self-reported emotions and their neural underpinnings. […]

Advances in connecting neural stimulation to physical control of the body are transforming the development of prosthetics and therapeutic training for people with disabilities, according to new research. […]
